What is the best way to have permalinks structured?
Did I make the right choice?
If I were to do it over (when I start my next site) would I do the same thing?
How hard would it be to change to a different structure?
What about all the links to specific articles both throughout the interweb and my own deep links?
What are some of the pros and cons of different methods?

These are some of the questions that I have been thinking about from time to time and lately I have again been hit with this “second guess” bug. Before I ever started this site, I read this post about SEO Friendly URLS and agreed that it would be better to use something besides the “?p=123″ method.

Based on the information in that post, the fact that it was the method used by John Chow, and since I had never done anything like this before, I went ahead and used the name only permalink structure that my posts currently have.

I have noticed that many of my fellow bloggers use a /month/day/title method for their posts and wonder if perhaps this might not be a bit better choice. I’m not sure what would happen if I tried to give two posts the same title, but I’m not sure I want to find out (if I haven’t already done it) and with the date/name based method, this wouldn’t be as big of an issue as they would have different /month/day/ portions in their URL.

On the other hand, are there SEO benefits or drawbacks to one method over the other and how about as far as professionalism and image? Do any of these things even matter that much?

It’s probably too late to change it now, but I want to open up the comments to anyone who reads this post as to your thoughts on this issue and what your recommendation would be. Also, what experience have you had with any particular permalink structure?

Like so many things in the world of blogging, there probably isn’t one best way, but I just figured I’d see what kind of discussion we can get going and perhaps validate my current setup or know what I would do differently next time. Oh, and I’m pretty sure that changing from one method to another on an established site like this one is probably out of the question.
